Abstract
Cette invention concerne un plot réflecteur pour chaussée routière à noyer dans des évidements ménagés dans le revêtement de la route pour signaler, la nuit, les limites centrale et latérales des voies de circulation. Réfléchissant la lumière des phares d'automobile, l'objet de l'invention a un corps principal discoïde destiné à être noyé dans un trou pratiqué dans la chaussée de façon à être en affleurement et non pas en saillie. Le corps principal du plot réflecteur est en caoutchouc et sa face supérieure comprend de petites particules de verre noyées dans la masse et couvrant toute la surface exposée du plot. Dans une variante, les particules de verre sont réparties sur toute l'épaisseur du corps principal en caoutchouc qui est collé au fond de l'évidement ménagé dans la chaussée. L'objet de l'invention de l'invention a un prix de revient bas et convient aux chaussées des régions enneigées où il ne risque d'entraver les opérations de déneigement du fait qu'il ne dépasse pas de la surface du revêtement.
